Circumstellar Disks in the Outer Galaxy: the Star-Forming Region NGC 1893 (2008)
Caramazza, M., Micela, G., Prisinzano, L., Rebull, L., Sciortino, S., Stauffer, J. R.
It is still debated whether star formation process depends on environment. In particular it is yet unclear whether star formation in the outer Galaxy, where the environmental conditions are,...

X-ray properties of protostars in the Orion Nebula (2008)
Prisinzano, L., Micela, G., Flaccomio, E., Stauffer, J. R., Megeath, T., Rebull, L., ...
The origin and evolution of the X-ray emission in very young stellar objects (YSOs) are not yet well understood because it is very hard to observe YSOs in the protostellar phase. Using COUP data, we...
X-ray properties of protostars in the Orion Nebula (2007)
Prisinzano, L., Micela, G., Flaccomio, E., Stauffer, J. R., Megeath, T., Rebull, L., ...
The origin and evolution of the X-rays in very young stellar objects (YSOs) are not yet well understood since it is very hard to observe YSOs in the protostellar phase. We study the X-ray properties...
Million-Degree Plasma Pervading the Extended Orion Nebula (2007)
Guedel, M., Briggs, K. R., Montmerle, T., Audard, M., Rebull, L., Skinner, S. L.
Most stars form as members of large associations within dense, very cold (10-100 K) molecular clouds. The nearby giant molecular cloud in Orion hosts several thousand stars of ages less than a few...
Accretion and Outflow-Related X-Rays in T Tauri Stars (2007)
Guedel, M., Briggs, K., Arzner, K., Audard, M., Bouvier, J., Dougados, C., ...
We report on accretion- and outflow-related X-rays from T Tauri stars, based on results from the "XMM-Newton Extended Survey of the Taurus Molecular Cloud." X-rays potentially form in shocks of...
The X-ray activity-rotation relation of T Tauri stars in Taurus-Auriga (2007)
Briggs, K. R., Guedel, M., Telleschi, A., Preibisch, Th., Stelzer, B., Bouvier, J., ...
The Taurus-Auriga star-forming complex hosts the only population of T Tauri stars in which an anticorrelation of X-ray activity and rotation period has been observed. We have used XMM-Newton's...
The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST) (2006)
Guedel, M., Briggs, K. R., Arzner, K., Audard, M., Bouvier, J., Feigelson, E. D., ...
(abridged:) The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST) surveys the most populated ~5 square degrees of the Taurus star formation region, using the XMM-Newton X-ray...
A Sensitive Search for Variability in Late L Dwarfs: The Quest for Weather (2006)
Morales-Calderon, M., Stauffer, J. R., Kirkpatrick, J. Davy, Carey, S., Gelino, C. R., Navascues, D. Barrado Y, ...
We have conducted a photometric monitoring program of 3 field late-L brown dwarfs looking for evidence of non-axisymmetric structure or temporal variability in their photospheres. The observations...
Spitzer Observations of G Dwarfs in the Pleiades: Circumstellar Debris Disks at 100 Myr Age (2005)
Stauffer, J. R., Rebull, L., Carpenter, J., Hillenbrand, L., Backman, D., Meyer, M. R., ...
Fluxes and upper limits in the wavelength range from 3.6 to 70 microns from the Spitzer Space Telescope are provided for twenty solar-mass Pleiades members. One of these stars shows a probable mid-IR...
